Homes on the Willoughby ridge
Willoughby's streets run along a ridge with Federation cottages, interwar bungalows and solid post-war brick homes. Some of the oldest buildings are on or near Penshurst Street, including Laurel Bank cottage from 1884. The suburb has no train station of its own, with Artarmon station on its western edge, so most homes are houses rather than towers.
The big exception is the former Channel Nine site, where the TV tower came down from 2021 and hundreds of new homes are planned. Elsewhere, typical jobs are kitchen and bathroom renovations, rear extensions, re-roofing and timber floor restoration. Houses facing the Gore Hill Freeway along the southern edge often ask about quieter windows. Many interwar bungalows here still have face brick, original timber floors, leadlight and picture rails worth protecting during the work.
Bushland gullies and old tip sites
Bushland gullies run off the ridge towards Middle Harbour. Flat Rock Gully, with its walking tracks down to Long Bay, was built on an old rubbish tip. If you live near a gully or a former landfill, a few things are worth knowing:
- Blocks near bushland may be mapped as bushfire-prone, which can raise building standards for decks and additions.
- Willoughby City Council protects many trees, so get approval before removing or heavily pruning one.
- Stormwater from your block must go to the street or an approved system, not into the bush.
- If you plan to dig near a former tip, ask council what is known about the ground first.
Next door to Castlecrag
Willoughby's postcode, 2068, also covers Castlecrag and Middle Cove. Castlecrag was designed by Walter Burley Griffin and Marion Mahony Griffin, and the Griffin conservation area there aims to keep buildings subordinate to the landscape. The Land and Environment Court has refused a large house in Castlecrag for failing that principle.
If your 2068 address is in Castlecrag, expect much tighter design rules on bulk, materials and tree loss than in Willoughby itself. Willoughby City Council has 12 conservation areas in total, so check the Willoughby LEP 2012 heritage maps for your exact street. Council has also proposed adding Griffin-era features in Castlecrag, such as an old stone retaining wall and a culvert, to its heritage list. See the North Shore hub.

Common questions
Is Castlecrag part of Willoughby?
Castlecrag is a separate suburb, but it shares the 2068 postcode and Willoughby City Council. The Griffin conservation area in Castlecrag has much stricter design controls than most of Willoughby suburb. Check your actual suburb and the Willoughby LEP 2012 heritage maps before you plan an extension or new house.
Can I remove a tree on my Willoughby property?
Not without checking. Willoughby City Council protects many trees on private land, and removing or pruning one without approval can lead to fines. Apply to council first. If the tree is near a planned extension, deck or driveway, an arborist's report will help council and trades understand what's possible.
Will the Gore Hill Freeway affect my renovation?
If your home faces the freeway, traffic noise is likely to be part of the brief. Acoustic glazing, seals, solid doors and insulation can help. Ask whether your council or certifier has specific noise requirements for new rooms. Our retrofit double glazing guide compares the options.
